GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 362,968, dated Mayl7, 1887.

Application filed June 26. 1886.

To all whom it may concern:

Be it known that I, Janus IRWIN, of West Bellevue borough, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gas Burners; and I do hereby declare the following to be a full, clear,'and exact description there of, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical sectional view of my improved burner on the line x :0 of Fig. 2. Fig. 2 is a horizontal section on the line 3 3 of Fig. 1.

Like letters of reference indicate like parts in each.

It is the object of my invention to provide a burner which shall be capable of burning naturnal gas successfully. This gas, while good for heating purposes, normally burns with a pale flame, and few, if any, of the burners heretofore in use have been of such construction as to obtain good results from it as an illuminant.

I shall now describe my improvcment,so that others skilled in the art to which it appertains may manufacture and use it.

In the drawings, a represents the burnershell, which is a metal casting having a central cavity, 7), threaded ends 0 (Z, and an annular lateral flange, 6. Extending radially through the flange 0 to the chamber I) arejetpassages f, arranged at any suitable distance apart, and extending from the passages f through the flange e are vertical jet-passages f, (preferably of smaller diameter than the holesf,) and inclined passagesf'*,also extendingthrough the flange 0 from the passages f. The gas-pipe h projects into the burner-shell and is perforated for the admission of gas to the chamber 0. The pipe is threaded at h and is screwed into the threaded end (2 of the shell to. The other end of the shell is closed by a screw-plug,j. The perforations of the pipe It should be small, so as to prevent the light from being injuriously affected by sudden variations in the gas-pressure. The chamher I) constitutes a reservoir for containing a quantity of gas, and acts, in connection with the finely-perforated tube 71 ,to prevent a strong pressure of gas in the pipe from causing the burner to blow, and thereby obviates largely the waste and imperfect combustion due to this cause.

The operation is as follows: The gas from Serial No. 206,287. (No model.)

the burner-shell escapes through the passages f, f, and f The lateral jet-passages f and f reduce the pressure of the gasjets from the main jet-passagesf, prevent it from blowing, as it otherwise would, and when ignited, the jets from the passages f andf curling up around the edge of the flange 6, re-cnforce thejets from thclargerpassages,f, and thicken the flame, as at 13, thereby so increasing the combustion of carbon in the gas that the luminous character of the flame is bettered, and it is rendered white and steady, when otherwise it would be pale and ofadiffereut shade. By practical experience I have found that so little of the carbon in the gas burned in this burner is unconsumed that if a white plate be held over the flame it will not be apple ciably dinn'ned.

An additional useful function of the jets f and f is that they impinge directly upon the burner-shell and increase its heat and theheat of the contained gas, so that the latter escapes from the chamber 1) into contact with the exernal air in a highly-heated condition, and as no air is admitted to the chamber 1) deposits of carbon will not occur in the jetpassagcs. The burner is simple and cheap, not liable to get out of order, and is especially efficient when used with natural gas.

If desired, either set of auxiliary jetpassages f or f may be omitted and the other used singly, or there may be any number of the auxiliary jet-passages more than two.

hat I claim as my invention, and desire to secure by Letters Patent. is

1. A gas-burner having lateral jet-passages and auxiliary jet-passages which lead from said first-named jet-passages, substantially as and for the purposes described.

2. A gas-burner having a flange, 0, jet-passages f, extending therethrough, and auxiliary jet-passages leading from the jet-pas sagesf, substantially as and for the purposes described.

3. A gas-burner having a flange, c, jet-passages f, extending therethrongh, and auxiliary jet-passagesf and f, leading from the j et-passages f, substantially as and for thepurposes described.

In testimony whereof I have hereunto set my hand this 21st day of June, A. D. 1886.

JAMES IRVIN.
